I guess not so "Newby" is asking for tips regarding crankshafts. My tip: leave it alone until there are more convincing symptoms that may show problems in the declared use, if that is truly the limit of the performance needs. Years ago I drove a Model A regularly, almost daily. The many miles were driven with cheap almost discarded engines that were patched up to go a few extra miles. Trouble most often was at the center main and I knew the sound well. In this real world, such strategy probably would not work as well excep perhaps in the imagination of one who does not want to do an engine in the style that shops practice these days. There may well be as many good used engines available in BC as we have here in Los Angeles which could shift the choices toward used, which could include counterweighted crank. Good Luck: Fred A
